bine is enclosed within'the heat exchanger of the apparatus to thus simplify the operation of the device by allowing the f'fluid discharging from the turbine to flow directly into the interior of the heat exchanger.

Another object of this invention is to provide a heat exchange apparatus adapted for heating or cooling, the location of which is dependent only upon the presence of adequate drainage for the spent fluid temperature modifying medium and a source of'such fluid temperature modifying medium under pressure.-

Hence, as is the case with so-called unitheaters the device of this invention may be installed any place to which supply and return piping can be brought. I

With the above and other objects in view, which will appear as the description proceeds, this invention resides inthe novel construction, combination and arrangement of parts substantially asvhereinafter described and more particularly defined by the appended claims, it being understood, that such changes in the precise embodiment of the hereindisclosed invention may be made as come within the scope of the claims.

The accompanying drawings illustrate one complete example of the physical embodiment of the invention constructed according to the best mode so far devised for the practical application of the principles thereof, and in which:

Figure 1 is a view partially in side elevation and partially in longitudinal section illustrating a heat exchange apparatus embodying this invention, parts thereof being broken away and shown in section to more clearly illustrate the apparatus;

Figure 2 is a horizontal, cross-sectional view through the apparatus taken on the plane of the line 2-2 in Figure 1; and

Figure 3 is a detail sectional view taken through Figure l on the plane of the line 3-3 of Figure 1.

Referring now particularly to the accompanying drawings, the numeral 5 designates generally an upright substantially cylindrical chamber which constitutes the heat exchanger of the in- 3 Claims. (Cl.'257137) stant apparatus. The side wall 6 of this chamber is formed of relatively thin metal pleated as shown in Figure 2 to define a multiplicity of narrow passages 1 in which the fluid heat exchange medium flows to the bottom of the chamber to reach a drain 8.

The exterior pleats which define the narrow passages I form vertical fins over which the air to be heated or cooled is caused to flow by an air impellor 9. ,The top and bottom ends of the narrow passages I are closed preferably by pinching the side walls thereof together as at H) (see Figure 3). The bottom of the chamber 5 is a substantially conical wall I I joined to the pleated side wall by means of a ring [2. The drain 8 leads from the bottom wall H to carry off the spent fluid heating medium.

The top of the chamber 5 is similarly closed by a conical w-all l3 joined to the pleated wall by means of aring l4. 7 The impellor 9 is fixed to a shaft l5 which extends down through the top wall l3 into the interior of the chamber 5 and is journaled in bearings I6 and H. The bearing 16 is carried by the top wall l3 while the bearing 11 is mounted in a partition wall 18 of substantially the same construction as the top 'wall l3. Both bearings 16 and 11 are preferably set in rubber to insure quietness and the bearing I! is a combination thrust and radial hearing.

A turbine 19 or other suitable power unit is fixed to the shaft I5 in the upper portion of the chamber 5, and directly beneath the turbine 19 is a conical deflector '20. The deflector 20 serves to direct spent fluid discharging from the turbine radially outwardly into the narrow passages I. The partition l8 has the same function in addition to supporting the bearing l1. Hence, assurance is had that all fluid discharging from the turbine flows down through the narrow passages I in contact with the walls thereof so as to provide for more effective heat transfer between such fluid and the air flowing over the exterior of the chamber 5. The deflector 20 and the partition l8 also serve to stiffen the chamber 5.

Fluid temperature modifying medium under pressure is delivered to the turbine l9 by a supply line 2| connected through a control Valve 22 with a nozzle 23. Hence, it will be evident that the fluid temperature modifying medium issuing as a jet from the nozzle 23 and striking the blades of the turbine l9 drive the same and consequently the air impellor 9 and that the spent fluid leaving the turbine is thrown out into the narrow pas- 3 sages 1 defining the upright side walls of the heat exchanger 5.

Efficiency is thus assured both from the standpoint of the transmission of power to the impellor 9 and the utilization of the heat (or cold) of the temperature modifying medium.

The entire structure is enclosed within a casing 24 preferably also cylindrical and of a size to constrain air flowing therethrough into contact with the outer surfaces of the narrow passages I. To this end the sides of the casing 24 are closely adjacent to the sides of the heat exchanger and the bottom of the casing is provided with a grilled air inlet 25 while the top thereof has a screened air outlet 26.

From the foregoing description taken in connection with the accompanying drawings, it will be readily apparent to those skilled in the art that this invention provides a simple, efiicient heat exchange apparatus which may be produced at relatively low cost and which may be readily installed in any location to which fluid temperature modifying medium can be piped.

What I claim as my invention is:

1. Heat exchange apparatus comprising: an upright substantially cylindrical chamber having a side wall formed of relatively thin metal pleated to define a plurality of narrow passages opening to the interior of the chamber with the exterior surfaces of said passages forming vertical fins; a drain leading from the bottom of the chamber; a top wall for the chamber; a bearing centrally mounted on said top wall; another bearing axial with said bearing and disposed inside the chamber; means supporting said other bearing from the pleated sidewall of the chamber; a shaft journaled in -said bearings and projecting above the bearing on the top wall; an air impeller fixed to the upper end of the shaft; a turbine fixed to the shaft at a point substantially directly beneath the top wall thereof, said turbine being adapted to discharge spent fluid therefrom directly into the interior of the chamber; a substantially conical deflector supported by the;

pleated side wall of the chamber and located under the turbine substantially adjacent thereto to deflect all fluid issuing therefrom radially outwardly into the narrow passages formed by the pleats in the side wall of the chamber to assure that all of the spent fluid will flow downwardly over said inner surfaces for substantially the full vertical height thereof; means for delivering fluid temperature modifying medium under pressure to said turbine to effect rotation of the turbine and said air impeller; and a casing open at its top and bottom ends surrounding said chamber and spaced therefrom whereby air circulated by said air impeller is drawn into the casing through the bottom end opening so as to be circulated upwardly over the exterior surfaces of the chamber for the entire vertical length thereof;

2. A heat exchange apparatus, comprising: an upright chamber the side walls of which are vertically pleated to define narrow vertical passages; a drain leading from the bottom of said chamber; a vertical shaft rotatably mounted within the chamber and projecting from the top thereof; an air impeller fixed to the upper end of the shaft to draw air upwardly over the exterior surfaces of said chamber and between the pleats in its side walls; a fluid pressure responsive power unit connected to said shaft and disposed within the upper end portion of said chamber, said power unit being adapted to discharge all of the spent fluid radially outwardly against the walls of the chamber surrounding the powerumt so that spent fluid impinging the chamber walls flows downwardly over the inner surfaces of the chamber walls and said narrow passages to the bottom of the chamber and into said drain; and means for delivering a fluid temperature modifying medium under pressure to said power unit.

3. Heat exchange apparatus as defined in claim 2 further characterized 'by the provision of a deflector under said power unit substantially adjacent thereto, said deflector having outwardly and downwardly sloping walls to assure that all of the spent fluid will flow downwardly over the inner surfaces of the chamber walls and the narrow passages defined by "the pleats in the chamber walls for substantially the full vertical height of the chamber.
